Very interesting.  I am contemplating my first BGA design with gEDA
tools (AT91SAM9G45, Atmel ARM9).  The part is a 18 x18 =324 ball device
with row designators marked as A-V (missing I,O,Q,S,...).  The Pin
designators are labels K16, R2, G7, .. with the Alpha first, followed
with the number.  I tried to put in a pin label like this, but
encountered problems with the online tool at
(http://vivara.net/cgi-bin/djboxsym.cgi).  

Has anyone been making BGA parts with multiple symbol files?  
If so, what do I need to look out for as I go down the development path?
(Will multiple symbols process as multiple items on the BOM?,  Will the
netlister correctly pickup the different symbols.  Can Alpha-number
designators be used at all?  

Thanks in advance
Mike
